4.3 CUTTING/RAPID SWITCHING FUNCTION
(1) Overview
Increasing the gains of the position loop and velocity loop is effective
in the improvement of cutting profiles. However, the maximum
feedrate and the acceleration of acc./dec. in rapid traverse are
generally higher than those in cutting feed. So, vibration in the
velocity loop or hunting in the position loop may occur in rapid
traverse even when stable cutting feed can be performed with the same
settings. To prevent this problem, the functions below are provided
with a function for switching between parameters for cutting feed and
parameters for rapid traverse.

NOTE
1 The TCMD filter and resonance elimination filter
can be used at the same time by parameter setting.
2 The cutting/rapid switching function is not applied
to the resonance elimination filter.
